MILK-BOTTLE CLOSURE THE LIKE.

, Application filed September 29, 1921. Serial No. 504,173.

i of which the" following is a specification.

paper I y when the milk is-delivered. The closure of This invention has to do with an improved closurafor milk bottles and the like. It has reference particularly to a removable closure for milk bottles which may be.attac-hed by the'user in place of the ordinary cap or other closure on the bottle the present invention may, however, be used to advantage for other purposes than the one just above mentioned.

One of the objects of the invention is to provide a closure which may be very easily attached to the upper portion of the bottle, and which when attached will close the bottle ina practically air tight manner. In this connection, another object is to provide a closure which may also be purposely removed from the bottle and be used over and over again on different bottles.

Another object of the invention is to provide a closure which is so constructed that it may also'serve as a valve for permitting the discharge of the contents of the bottle under the convenient control of theuser. In

this connection, another object is to so arrange the parts that when the milk or other contents are being discharged they will flow through a spout so thattheir discharge may be conveniently directed.

Other objects and uses of the -invention are to so arrange the closure that it will normally remain in closed and practically air tight condition, and to provide a closure which may very cheaply and easily be manus factured from stampings or other simple manufacturing processes.

'Other objects and uses of the invention will appear'from a detailed description of the same, which consists in the features of construction and combinations of parts hereinafter described and claimed.

In the drawingi Figure 1 shows a fragmentary view of the upper portlon of a bottle'having applied thereto a closure embodying the features of the present invention;

Fig. 2 shows a vertical section corresponding to Fig. 1; and q Fig. 3 shows a plan'view corresponding to Fig. 1. Y

Referring to the drawing,'the closure is shown as being applied to the upper portion of a milk bottle or the like 4; The upper portionof bottles of this class is generally enlarged a shown at 5 in Fig. 2 to provide ,a more or ess distinct shoulder at the point 6. The inner portion of the neck is alsousually provided with a sill 7 on which the paper cap is initially seated. After removing this paper cap the closure of thewpresent invention may be substituted.

The present closure includes a disk 8 of sheet rubber or other suitable material having the elastic downwardly depending collar or flange-portion 9 which preferably terminates in thelower beaded edge 10. The parts face of the disk 8 and overlies the opening shaped valve 12 seats up against the bottom 11, so that when said disk 12 is raised into the position of Fig: 2 its edge portion will seat firmly against the bottom surface of the rubber'disk and hermetically close the opening 11. For this purpose, 'it is preferred that the disk 12 should be of concavo-convex form as shown in Fig. 2, so that its edge will seat before its body portion. A stem 13 is secured to the centralportion of the disk 12, and is conveniently provided with v a top'button 14 which may-be, presseddown by the finger so as 'to force the valve 12 away from the disk 8. A spring 15 surrounding the stem 13 retains the stem and valve normally in the raised closed position.

A metal disk 16 is preferably seated on top of the disk 8 so as to provide a-convenient abutment for the lower endof the spring 15, andalso to guide the stem 13 'in its movements. Such disk 16 when used should preferablybe of sufficient size to overlie at least" a portion of the neck of the bottle itself as shown in Fig' 2. Such disk should also be provided with a perforation 17 in registry with the perforation 11 of the disk! It Is also desirable when the disk 16 is used to turn its edge' 18 upwardly away from the It is observed that the spring serves by c pressing down against the disk 16 and by drawing the valve 12 upwardly to clamp the 15 andcthe valve. As soon as the button lt'is disk 8 so'that the metal will not cut the rubber.

The disk 16 when used may also be provided with. aspout 19 'of convenient form and position to direct the other contents away from the opening. Such spout when used may be made as an integral,

portion of the disk .16, the entire arrangement being stamped out from sheet metal.

rubber disk '8 securely between the disk 16 depressed-'tocarryf the valve away from the rubber disk, the pressure of the spring against the disk 18 is increased, so thatthe parts are also kept in firm engagement with each other. It is also observed that with this arrangemen't it is possible to very thoroughly cleanse the entire device, since the disk 16 may be lifted away from the rubber disk in order to permit water and other cleansing agent to freely enter between all of the disks.

While we have herein shown; and described only a single embodiment of the featurns of our present invention, still we do not limit ourselves thereto except-as'we may do so in the claims.

i We claim: v c, i

1. As a new article of manufacture,, a closure for milk bottles and the like comprising in combination a rubber disk having a downwardly depending flange with a pcripheral bead, of size suitable 'to set down over the upper portion of the neck of the bottle, there being an arcuate perforation .in said disk, a sheet metal disk seated on top 7 of said rubber disk and provided with an arcuate perforation and of size and location a to register with thejperforation ofthe rubclosure for {milk bottles and the like comher disk and being further provided withan upwardly and outwardly extending spout,

a concavo-conve'x disk valve "beneath the rubber disk with its concave side facing upwardly, a stem centrally secured to said valve disk and extending up through the rubber disk and the top-disk, and a spring surrounding said valve stem above the top disk and tending to draw the valve disk upwardly against the rubber disk 1 and 'to force the top disk down against the rubber disk, substantially as described.

2. As a new, article of manufacture, a

substantially a'sdescribed;

prising in combination a rubber 'disk having a downwardly depending flange of size suitable to set down over the upperportion of the bottle, there being a perforation in said disk, a sheet metal disk seated on top.

of said rubber disk and provided with a perforation of size and location to register with the perforation of the rubber disk and being further provided with an upwardly and outwardly extending spout, a disk valve beneath the rubber disk, a stem secured to said valve disk extending up through therubber disk and the top .disk and a spring surrounding said valve stem above the top.

disk and tending to draw the valve disk upwardly against the rubber disk and to force the top disk down against the rubber disk, substantially as described.

3. As a new article of manufacture, a closure for milk bottles and the like comprising in combination a rubber disk having a downwardly depending'flange with a peripheral head of size suitable to set down over the upper portion of the neck of the disk, a sheet metal disk seated on top of said rubber disk and provided with a perforation of size and location to register with the perforation of the rubber disk, a disk valve beneath the rubber disk, a stem secured to said valve disk and extending up through the rubber disk and the top disk, and a springbetween the valve stem and the topdis'k tending to draw the valve disk upwardly against the rubber disk'and to force the top disk down against the rubber disk,

4 As a new article of manufacture, a closure for milk bottles and the like comprising in combination a sheetmetal disk aving an upwardly and outwardly extending spout, a rubber flange in conjunction with the under face of said disk and under underlying the disk, an upwardly extending stem secured to the disk valve and reaching upwardly through the disk, and aspring between said stem and the disk tending to 'drawthe valve disk upwardly, substantially as described.
